"Caves"by Belén, 6B

Hi classmates,Last term I read "Caves" in the English classroom.This book tells us about caves.Now I know that:

* The Mammoth Cave in Kentucky in the USA is the biggest cave system in the world.* Most caves are limestone caves.* It can take one year for a stalactite to grow 2 centimetres.* Ice caves are the most dangerous kinds of caves.* The longest lava cave is in Hawaii and is more than 11 kilometres long.In the book there is also a story " The lucky accident".The story is about four children who discovered an amazing cave with paintings more than 20, 000 years old!.
